This paper presents an approach for the inverse dynamic analysis of a spatial four-bar linkage mechanism. By employing the Lagrange multiplier formulation with redundant generalized coordinates for closed-loop mechanical systems, expressed in both analytical and matrix forms, and combining it with the orthogonal projection method for establishing coordinate systems, the equations of motion of the mechanism are derived. Based on these equations, the driving torque applied to the input link is determined. The obtained results can be used for the analysis and design of mechanical systems with similar configurations, such as shaper mechanisms, hydraulic presses, and related machinery.
